As for the second, it's highly likely that "Breaking Bad" will score its highest-ever rating.

Until this year, "Breaking Bad" was a critics' darling but still a niche show, with viewership in the 3 million to 4 million range. But over the last few weeks, as reviewers have rhapsodized over the final few episodes and anticipation over the finale has reached a fever pitch, viewing has exploded.

Last Sunday, with its penultimate episode, "Breaking Bad" set a record with 6.6 million total viewers, according to Nielsen.

This week, the finale is almost certain to do more than that. At least 7 million seems a safe guess, but it could go much higher, if many curiosity seekers and casual fans show up.

However, it would tough for "Breaking Bad" to set a record for cable TV generally, or even for AMC. After all, in April the Season 3 finale of the zombie smash "The Walking Dead" was seen by 12.4 million viewers.
